Abstract

The nozzle has a peripheral wall (1a) with thickness greater than or equal to diameter of a transversal hole (4), so that an end of a coolant outlet duct is fixed in the hole. The wall is thin due to the presence of an external recess (1d) opposite to a hole of a transversal fixing plate (6). A nozzle body and a fixing screw have a small axis distance between them which is sufficient to rotate a screwing tool on a screw head. The external recess is in a portion opposite to the hole, and permits to connect axes of the nozzle body and the fixing screw.
